  1. The addition of the cumulative totals of number resources held by an organization using the baselines of /24s for IPv4 and /48s for IPv6, and
  2. Additional detail showing what a Legacy Resource holder organization’s service category and corresponding fees would be without the Legacy RSA Fee Cap.

ARIN recovers the cost of its registry operations through annual fees charged to registry customers. All new ARIN customers must sign a Registration Services Agreement (RSA) to receive registry services.

In accordance with the RSA, all fees paid to ARIN are non-refundable. Fees may not be prorated, are nontransferable, and must be paid in full. All fees are payable in USD (United States Dollar) only.

Registration Services Plan

Customers with IPv4 and/or IPv6 number resources pay annually for an appropriately sized Registration Services Plan (RSP) that provides registry services for all their number resources (IPv4, IPv6, and ASNs) in the ARIN registry. Customers with only ASN’s are not eligible to participate in a RSP and instead pay an annual fee for each ASN as specified below.

Organizations must pay the annual fee for their RSP plan as determined by the service category table below at the time the initial request for number resources is approved. This payment is considered an initial fee when an organization is receiving number resources for the first time from ARIN and will establish the anniversary date for future annual RSP payments. Future annual payments will be based on the appropriately sized RSP category as determined by the aggregate holdings of IPv4 and IPv6 number resources held on the anniversary date.

As of 1 January 2022, all previous end-user and LRSA organizations have been transitioned to Registration Services Plans of the appropriate-size RSP category as determined by their aggregate IPv4 and IPv6 resources held.

RSP Service Categories and Fees

The table below displays the annual Registration Services Plan fee per service category for ARIN customers. The aggregate block size consists of the total IPv4 or IPv6 resource holdings of an organization.

Service Category Fee IPv4 Aggregate Block Size IPv6 Aggregate Block Size
3X-Small* $250 /24 or smaller /40 or smaller
2X-Small $500 Larger than /24, up to and including /22 Larger than /40, up to and including /36
X-Small $1,000 Larger than /22, up to and including /20 Larger than /36, up to and including /32

4X-Large $128,000 Larger than /8, up to and including /6 Larger than /8, up to and including /4
5X-Large $256,000 Larger than /6 Larger than /4

*There is a temporary IPv6 fee waiver for organizations in the 3X-Small service category. A 3X-Small organization may receive registry services for up to a /36 of total IPv6 space and remain in the 3X-Small service category. This waiver will expire 31 December 2026.

Legacy Resource Service Agreement (LRSA)

Organizations with resources held under a LRSA receive the same Registration Services Plan for their legacy resources only with the difference being ARIN provides a fee cap on total annual fees for LRSA customers. The total annual fees applicable to legacy resource holder organizations are limited to $150 annually for 2022, regardless of the number of IPv4 legacy resources held under a LRSA. ARIN will increase this annual cap of registry fees for LRSA customers by $25 per year.

Transactional Fees

Transactional fees are for those services that are not covered under a Registration Services Plan. These fees are non-refundable.

Transaction Type Fee
ASN Issuance (per ASN) $550
ASN Annual Fee (per ASN for ASN only resource holders) $150
Organization Create $50
Organization Recovery $100
Specified Transfer Listing Service (STLS) per listing (source + recipient) $100
Specified Transfer Listing Service (STLS) Facilitator (annual) $1,000
Transfer Charge - 8.2 Mergers, Acquisitions, and Reorganizations Resource Transfers (requesting organization) $500
Transfer Charge - 8.3 Resource Transfers Between Specified Recipients Within the ARIN Region (source only) $500
Transfer Charge - 8.4 Inter-RIR Transfers to Specified Recipients (source only) $500
Premier Support Plan for XL and smaller customers (annual) $5,000

Autonomous System Numbers (ASNs)

An organization will be invoiced a transaction fee of $550 for each new ASN approved. The ASN will be issued once payment of the invoice is received.

ASN Only resource holders are responsible for an annual fee of $150 per ASN.

Note: For Organizations with ASNs receiving services under a RSP, the annual fee does not apply.

Organization Create / Organization Recovery Transactions

ARIN will collect a transaction fee for each Organization Create or Organization Recovery. The transaction fee payment is required before evaluation of the request begins.

  • Organization create is $50.00 per transaction.
  • Organization recovery is $100.00 per transaction.

Specified Transfer Listing Service (STLS)

The fees for the STLS are independent of resource transfer fees and assessed separately, payable on approved application to the service:

  • Source and recipient organizations: a one-time $100 fee for each approved listing request, no annual fee requirement, meaning they will incur no additional charges until their needs are met or their resources transferred.
  • Facilitator: pays an annual fee of $1,000 to participate in the service.

Refer to the STLS registration guidelines for full details on requirements and process.

Resource Transfers

ARIN will collect a $500, non-refundable transfer processing fee for each transfer request of registration rights to Internet number resources. Refer to the Transfer Resources page for full details on requirements and the process for transferring registration rights to Internet number resources. This fee does not guarantee approval of a transfer request.

The source and recipient organization must pay any outstanding annual fees before evaluation and any fees that become outstanding during the evaluation must be paid before completing any request.

The source (or legal successor) organization will be invoiced for each transfer request submitted; the transfer processing fee must be paid before evaluation of the transfer request begins.
